Some translations set each line of poetry farther to the right than the rest of the text to make it easier to read. The ULB does this with the poetry in this chapter.
The prophecies of this chapter focus on the coming Messiah. Some of these prophecies concern the first coming of Jesus, while some reference a future day of restoration. The author transitions between these time periods without telling his reader. (See: [[rc://en/tw/dict/bible/kt/prophet]] and [[rc://en/tw/dict/bible/kt/christ]] and [[rc://en/tw/dict/bible/kt/restore]])
It is uncertain what period of time these prophecies refer to or who will fulfill them. The translator should allow this uncertainty and ambiguity to remain. (See: [[rc://en/tw/dict/bible/kt/fulfill]])
